## Introduction

This repo provides an ini key=value storage backend for use with

 [args](http://github.com/thrawn01/args)

## Installation

```

$ go get github.com/thrawn01/argsini

```

## Usage

```go

    import (

    	"github.com/thrawn01/args"

        "github.com/thrawn01/argsini"

    )

	parser := args.NewParser()

	parser.AddOption("listen-address").Help("Specify local address to listen on")

	parser.AddOption("config").Short("c").Required().Default("/etc/app/config.ini").

	    Help("Specify configuration file")

	parser.AddOption("cache-size").IsInt().Default(150).

	    Help("Specify the size of the cache in entries")

	// Parse the command line args

	opt := parser.ParseOrExit(nil)

    // Create a new backend object

    backend := argsini.NewFromFile(opt.String("config"), "")

    // Load the config file specified on the command line

    opts, err := parser.FromBackend()

	if err != nil {

		fmt.Printf("config error - %s\n", err.Error())

	}

    // Print out the loaded config items

    fmt.Printf("listen-address: %s\n", opts.String("listen"))

    fmt.Printf("cache-size: %d\n", opts.Int("listen"))

    // Watch ini file for any configuration changes

    cancelWatch := parser.Watch(backend, func(event *args.ChangeEvent, err error) {

        if err != nil {

            fmt.Println(err.Error())

            return

        }

        fmt.Printf("Changed Event - %+v\n", event)

        // This takes a ChangeEvent and update the opts with the latest changes

        parser.Apply(opts.FromChangeEvent(event))

    })

```
